/** Test for style struct copy constructors **/

 * XXX Why doesn't putting a bug in the nsStyleFont copy-constructor for
 * font-weight (initializing to normal) trigger a failure of this test?
 * It works for leaving -moz-image-region uninitialized (both halves),
 * overwriting text-decoration (only the first half, since it's not
 * inherited), and leaving visibility uninitialized (only the second
 * half; passes the first half ok).
